BALING-MACHINE Specification of Letters Patent.

Patented July 23, 1907.

Application filed May 5, 1906. Serial No. 315,317.

To all whom it may concern:

Be it known that 1, STEPHEN MARTiN, a citizen of the United States,residing at West Jefferson, in the county of Madison and State of Ohio,have invented certain new and useful Improvements in Baling-Machines, ofwhich the following is a specification.

My invention relates to a baling machine, and has for its object theprovision of a device of this character adapted to receive strawdirectly from the threshing machine and to compress said straw intobales ready for the market.

A further object of the invention is the provision of a baling machinegeared in such manner that it is adapted to be belted directly to thecylinder of the threshing machine and to be driven therefrom and alsoadapted to receive the straw directly from the pneumatic chute of thethreshing machine, whereby the straw from the threshing machine may bebaled without an intermediate handling.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

in the accompanying drawings: Figure 1 is a view in side elevation of myimproved baling machine, illustrating the manner in which it is beltedto the threshing machine, Fig. 2 is an enlarged side elevation of thebaling machine, Fig. 3 is a longitudinal vertical section of said balingmachine, Fig. 4 is a plan view of said baling machine, Fig. 5 is a planview of a spring clip hereinafter described, Fig. 6 is a front elevationof a yoke hereinafter described, Fig. 7 is a vertical section of apacking head hereinafter described, and, Fig. 8 is a transverse sectionof the arm upon which said packing head is mounted.

Like numerals designate corresponding parts in all of the figures of thedrawings.

Referring to the drawings, the numeral 5 designates the body portion ofmy improved baling machine. This body portion comprises a top 6, abottom 7 and side walls 8, said side walls 8 being cut away at 9 and 10in the usual manner. This body is mounted upon wheels 11 and 12 and isprovided with a tongue 13. Cross bars 14, vertical rods 15, springs 16and tightening handles 17 form a tension device of the usual and wellknown construction.

Located upon the top of the machine and in line with the closed portionof the sides, is a hopper 18 adapted to receive straw through thepneumatic chute 19 of the threshing machine 20. This hopper is adaptedto be intermittently closed by a hay fork. This hay fork comprises tines21 and side rods 22, said side rods lying outside of the hopper andtraveling upon guides 23. Springs 24, one end of which are secured tothe rods22 as at 25, and the other ends of which are secured to a block26, carried upon the rear face of the hopper, tend to throw the forkformed by the tines 21 toward the rear wall of the hopper and therebyclose said hopper to the passage of straw. The bars 22 are connected bya cross member 27 to which a guiding arm 28 is secured as at 29. A yokeformed by vertical rods 30 is secured to the top 6 and has a dependingportion 31 in which is mounted a roller 32. This roller 32 serves tosupport the arm 28 and to hold the free end of said arm in position tobe engaged by a roller which is carried by the gear wheels as will bepresently set forth. The arm 28 is provided with transversely disposedlugs 33 located upon each side thereof, and the outer end of said arm isformed into a hook 34. A pulley 35 is secured to the shaft of thecylinder of the threshing machine indicated at 36 and said pulley isconnected by a belt 37 with a driving pulley 38. This driving pulley 38is fast upon a shaft 39 which extends transversely of the baling machineand has secured upon its opposite end a balance wheel 40. Secured uponthe shaft 39 are pinions 41. These pinions mesh with gear wheels 42which are fast upon a shaft 43. Pinions 44 are likewise secured uponthis shaft 43 and mesh with gear wheels 45 and 46. The gear wheels 45are mounted upon a shaft 47, while the gear wheels 46 are mounted upon ashaft 48.

As is best illustrated in Figs. 3 and 4, a pin 49 is secured between thegear wheels 45 and supports a roller 50 with which the hooked end 34 ofthe arm 28 is adapted to engage. Lugs 51 are carried by the spokes ofthe gear wheels 45 and serve the purpose which will be set forth in theoperation of the machine. One end of a connecting rod 52 is secured to awrist pin 53 carried between the gear wheels 46, while the opposite endof said connecting rod is pivoted to a wrist pin 54 carried by a plunger55, said plunger being slidably disposed in the body portion 5. Apacking head 56 is carried upon the end of an arm 57, the lower portionof which is curved as at 58 and pivoted at 59 to the connecting rod 52.The upper portion of this curved arm 57 passes through a yoke 60 whichis mounted for swinging movement on the shaft 39 and is provided withrollers 61 and 62 against which the front and rear faces of the arm '57hear. The end of the head 56 is provided with a metalshoe 63 which isslotted as at 64. Pins 65 pass through these slots and enter the head 56byvirtue of which construction the shoe 63 has a sliding engagement withsaid head. A spring 66 bears between the lower portion of the head andthe shoe and tends to force said shoe outwardly to its limit ofmovement. Springs 67, only one of which is shown, are located at eachside of an opening 68 formed through the front of the hopper. V-shapedsprings 69 and 70 project through the closed portion of the side wallsand serve to prevent the follower boards from falling over when they arefirst placed in position.

The operation of the machine is as follows: Straw is fed directly intothe hoppper 18 from the chute 19. As

the cylinder of the threshing machine rotates, the driving wheel 38 isrotated to the right in Fig. 1. This rotates the gear Wheels 42 to theleft and the gearwheels 45 and 46 to the right. The rotation of the gearwheels 46 imparts a reciprocatory movement to the plunger 55 through theconnecting rod 52. As the plunger moves forward to compress a charge,the roller 50 engages the hooked end 34 of the arm 28 and partiallywithdraws the fork formed by the tines 21 from across the hopper,permitting a charge of the incoming straw to descend through saidhopper. When, during the rotation of the gear wheels 45, the lugs 51contact with the pins 33, the hooked end 34 of the arm 28 is lifted fromthe roller and the fork formed by the tines 21 is caused to close thehopper under the influence of the springs 24, to thereby prevent morestraw from passing into the lower portion of the hopper. As the plungermoves rearwardly, the packing head assumes the position illustrated inFig. 2, packing the charge of straw into the body of the machine. As theplunger moves forward to compress the charge of straw into the balewhich is being formed, the head will be lifted out of the way, as shownin full lines in Fig. 3. When suflicient straw has been packed by theplunger to form a bale, a follower board is inserted between the springs67 and is prevented from dropping into the lower portion of the machineby the springs until the lower face of the arm 57 presses said boarddownwardly. Said board then drops into the lower portion of the machineand is held in a vertical position by the spring detents formed by thesprings69 and 70 until the plunger forces said board up against the endof the bale.

Heretofore it has been customary to bale the straw in a separateoperation from the operation of threshing, necessitating the employmentof an additional engine at a greatly increased cost. It has not requiredas much time to bale the straw as to thresh the wheat from which thestraw that is tobe baled, is derived. By making the operation ofthreshing and the operation of baling a simultaneous one and by gearingthe baler to the cylinder of the threshing machine, I am enabled to saveconsiderable time and labor, for the cylinder of a threshing machine isvery large and heavy and rotates at a high rate of speed. It is notnecessary to have the parts of the baling machine, rotate at nearly sohigh a speed and I am therefore enabled to gear said baling machine downto about forty revolutions per minute of the gear wheels 46 to which theplunger is connected. The cylinder of the threshing machine rotates atabout twelve-hundred revolutions per minute. Since it is necessary inthreshing the wheat, to have this cylinder rotate at a high rate ofspeed throughout the day, by connecting direct to the cylinder andgearing the baling machine down as shown and described, I am enabled tobale the straw in a continuous operation with the expenditure of a verysmall amount of power. The structure of the head illustrated in Fig. 7,provides a yielding head which prevents the arm 57 from being bent if anundue amount of straw enters the hopper to be forced down by said head.Angle plates 7]. are secured by pins 72 to the arm 57 and strengthen andbrace said arm laterally.

From the foregoing description, it will be seen that simple andefficient means are herein provided for accomplishing the objects of theinvention, but while the elements shown and described are well adaptedto serve the purposes for which they are intended, it is to beunderstood that the invention is not limited to the precise constructionset forth, but includes within its purview such changes as may be madewithin the scope of the appended claims.

What I claim, is:

In a baling machine, the combination with a body portion, of a hopperadapted to deliver straw to said body portion, a hopper closing memberhorizontally disposed in the hopper, a driving wheel, gear wheelsconnected to said driving wheel, an arm connected to the hopper closingmember, members carried by some of the gear wheels adapted to engage andimpart longitudinal movement to said arm, releasing members carried bythe gear wheels adapted to engage the said arm and release it after ithas been given a predetermined movement, a plunger, means for impartingreeiprocatory movement to said plunger, and a compressing memberconnected to said last named means and adapted to compress the strawinto the body portion of the machine and in front of the plunger.

In testimony whereof I afiix my signature in presence of two witnesses.

STEPHEN MARTIN.
